合成出了一硫化四甲基秋兰姆(TMTM)，采用溶剂蒸发法培养出了单晶TMTM，通过XRD单晶衍射仪、FTIR、TG-DSC对其进行检测和表征，揭示了单晶TMTM的微观结构和内在规律性。XRD单晶衍射从衍射数据、部分健长和键角, 揭示TMTM的微观结构，单晶TMTM高度有序化的定向排列结构，决定了其高效的橡胶硫化促进性能。TG-DSC从热效应分析TMTM的性质，FTIR、TG-DSC检测结果表明，单晶TMTM中蕴含很少许的二硫化碳，FTIR揭示了TMTM内部的化学键键型，和单晶衍射仪从不同侧面检测的结果一致，为确定TMTM的分子结构提供了实验依据。TMTM的分解温度偏高，为采用硫化仪研究TMTM的橡胶硫化性能提供参考。本研究为企业选定工作标准品，对TMTM工业化生产进行跟踪检测，评判TMTM的产品性能指标，填报立项TMTM化工行业标准的申报，撰写标准草案，完成国家工业和信息化部的标准制修订项目计划，提供基础实验数据。

Preparation of Rubber Accelerator Tetramethyl Thiuram Monosulfide and Its Spectral Analysis

In the study, rubber accelerator tetramethyl thiuram monosulfide (TMTM) was synthesized firstly. Single crystal TMTM was cultivated by solvent evaporation method. TMTM was detected and characterized by XRD single crystal diffraction, FTIR, TG-DSC. The micro-structure and intrinsic regularity were revealed. The TMTM microstructure was revealed by XRD single crystal diffraction from the diffraction data, part of bond length and bond angle. Its highly efficient performance of rubber vulcanization promotion was decided due to its orientation structure and high order. Properties of TMTM was disclosed by TG-DSC analysis from the heat effect. The results of TG-DSC and FTIR showed that single crystal TMTM possessed with little CS2. The chemical bond types in TMTM were revealed by FTIR the same as single crystal diffraction testing by different way. The decomposition temperature of TMTM was very high. It could provided reference with research on rubber vulcanizing properties by TMTM on rubber vulcanizing machine. This study can help the enterprises to designate the working standard tracing detection of TMTM industrialized production. Performance index of TMTM was judged. The project of TMTM industry standard can be declared by the enterprises, written a draft standard. It can provide the basis experimental data on completing the revision of the national ministry of industry and information technology standard system project plan.
